Whoops!  By imaginary, I meant not really on the internet, but in
198.168.x.x block reserved for private netting.

This combination of things seems to work in rc.conf:

network_interfaces="lo0 re0"
ifconfig_re0="inet netmask"

This seems to be the basic setup for all Clear hub modems for fixed
locations.  It may or may not be a step in the right direct for Clear mobile
hotspot type modems.

I also added the nameservers that the hub told me about to resolv.conf
although it is not clear to me that this is consulted.

tun0 will stomp all over this configuration (which is, as a reminder, wire
ethernet connection to Clear hub-modem) and pppoe is not pertinent on
your side anyway.  It is much simpler than I thought.  You can leave
/etc/ppp/ppp.conf alone in case you have to drop back - just don't invoke
tunX in rc.conf.

Also part of the learning experience before the original question: ethernet
cables are not created equal.  Use the one that comes in the modem box (four
wire), not some two-wire cable you have lying around.

Later today, dongles that will work with FreeBSD are expected to arrive, so
we will see whether it is possible to get wireless connections to the Clear
hub modem.
